Video and photos of an unusual glowing multi-colored ”mushroom cloud” hanging over Beijing skyline scared internet users who couldn’t make out what it was.

An unusual sight lit up Beijing skyline – a huge glowing mushroom cloud hung over the city around 7 pm local time.

It covered several miles and stayed in the air for about an hour, gradually taking the shape of an atomic bomb explosion. It then gave way to more surprises – a further spectacle of lightning strikes lit up the evening skies, making the site even more ominous.
